    摘要: In a method using a chromatographic separation apparatus consisting of plurality of unit packed beds each having a supply inlet/extraction outlet, wherein the apparatus is effectively divided into four zones; an adsorption zone, a refining zone, a desorption zone, and a concentration zone. A supply and extraction step is performed in which all of the fluid flowing out of the adsorption zone is extracted through the nonadsorbate fluid extraction outlet, and then a recycle step, in which no fluid is supplied to or extracted from the bed, is performed to move the concentration distributions in the bed to a desired position. As a result, the method requires fewer unit beds, and enables extraction of components of higher purity.
